A few drops will restore thickened nail polish to its correct consistency and make it easier to apply in thin coats. Two or three fine coats will last longer than a thick coat of nail polish that will flake or peel in a couple of days.
If polish is too thick, add one or two drops of THINNER and shake well. Let it stand for 20 minutes, shake again. It is now ready for use. Note: Never thin a nail polish with polish remover or acetone, as these two products will ruin the polish
